Salt Nic Expiration

Is there an expiration on salt nic juices? I purchased a bottle of 35mg salt nic and I’ve had the juice before but it tastes horrible. The colour and smell is fine, but like I said it tastes almost bitter. According to the label it was packaged in January 2019 and I’ve looked online for answers and all I get is, “unofficially salt nic should have the shelf life of freebase”.

Anybody with any experience in this?

The commonly used Benzoic Acid salt of Nicotine (which forms in ~1:1 molecular proportions) should be more stable than base Nicotine. That does not take into account the possibility of Benzoic Acid or Nicotine reactions with other components in juices. One bit of information found: 1 year shelf-life listed for dry/cool powdered Nicotine Benzoate, NicSalt-B. “Bitter” is generally associated with alkalinity; “sour” with acidity.

I read that darkening is attributed to the oxidation of Nicotine (which is increased by exposure to photons of light, and the oxidation product Cotinine has a yellowish tint), and as well as to (alleged) “caramelization” type reactions involving the various sugar-related molecules existing in various types of natural/synthetic flavors:

In most cases, the ingredients in your e-liquid cause it to turn dark or brown in the tank. A lot of e-liquids on the market have artificial sweeteners and sugars that add flavor.

When exposed to heat, the sugar in sweet e-liquids will caramelize and can change the color and texture of the liquid. It’s just like the process of making caramel, and the result can be just as gunky.

… though (at room temps), it seems that such reactions would proceed rather slowly - but may “add up” ?

The impact of light exposure on mixes that are themselves relatively dark (and thus not transmissive to light) is probably limited to a small percentage of molecules along the outer exposed surfaces of the liquid volume.

Could it have been exposed to heat or sunlight at all? I had an rta full of juice made with salt nic sitting on my kitchen table for 7 days, light yellow color when I left and when I got back in town it was dark red, only variable I can think of is that window gets about 4 hours of direct sun a day.

That’s all I can think of that caused it after what Raven posted, so I guess it’s the culprit

I suspect its just a bad batch. From my play with salts, they are quite resistant to heat. Also they sèem to turn darker as they go age / (go bad)
I am vaping some juice i made September 18 and its spent the whole time on a shelf under tv.

My older salts mixes will get gold/orangish colored but taste doesn’t change.

That’s interesting, it makes me wonder because like I said the colour is a translucent yellow… But this is also the best lab in Canada for juice too, so I DON’T FUCKING KNOW!

All I know is it cost me 25 bucks for a 30ml

Joel… lemme ask you this…

do you shake every single liquid when you mix?

It was bought recently and I don’t have a furnace in my apartment, just radiant heating

Does it suspended in pg? And how does normal pg taste for you?
This may seem far fetched, but a friend hated my high pg mix (40% is too bitter for him now) more and more because it taste more bitter to him. But I only know of 1 person though, so… Maybe?
Or maybe you got a bad batch (dont want to go there but it’s a possibility)

No issues with PG ratios and given the lab’s reputations for upholding the highest standards I doubt it’s a bad batch greatly. The shop I bought from is closed today, but was told to take it to them to try out and see if I can get a new(er) bottle and that maybe this was was just kept in the back and not rotated when stocking (put to the front of a batch of juice to sell faster)

if not, I’ll just go to premiumlabs.ca and complain

mmmm… no just tell them what is happening and see what they have to say…
many times a reseller/vendor will try to help out, if not replace it… but you have to be good! :slight_smile:

and he was asking how you perceive pg in general… is it bitter, tangy sweet etc by itself?

Well, I can’t honestly say what it tastes like because I haven’t bought PG in around 4 years, I’ve always mixed max VG. But to tastes flavours by themselves I’d say that there is a slight bit of bitterness to each one.

try your vg by it’sself… it should be bland but sweet…
